I did not see anyone compare this lens to the Zeiss Contax G Planar 45mm f2 lens, which I have been using on my A7r since the third party autofocus adapter has been available. The G45 is much smaller and inexpensive (around $300 2nd handed), while at f2 it is still very sharp, although the third party adapter does not autofocus fast ( takes more than 1 sec to do the autofocus) and is only AF-S, but for not fast moving objects, the combination works OK. It seems the G45's planar design is very good if it can be duplicated on an modern autofocus mechanism and sell at lower price!

Still disappointing that it does not have Wi-Fi and let Focus have a iPad / Androd version such that it can get live view on an iPad / Androd notepad, such that manual focusing when using the tilt/shift adaptor is easier, and more portable. I will keep my H4D-40 and wait further.

In reply to:

Timmbits: " it’s better to change the focal point by moving the lens physically back and forth rather than using the focus ring"

I am curious as to how to do this...

I'm imagining my camera on a tripod, and I have to move it by a fraction of a millimeter... how does that work?

Usually I am using three dimensions gear head when doing such macro photo, it n get very fine movements easily.
